Who makes the match barrel for PTR-91 the "FR" variant? And what kind of accuracy can you expect out of with decent ammo like FGMM with 168 grainers or similar?

It has a match bull barrel.

Barrel:
18” Bull Barrel 4140 Chromoly

Twist rate? Is it 1/11 or 1/10. I like heavier bullets for the 1/10. Like 175-208gr. I do 168 and lighter for 1/11 twist. You won't get bolt gun accuracy out of a semi auto. Is the barrel free floated. If barrel isn't free floated accuracy will suffer.

I think it was reported in the past as Thompson Center. Not exactly match grade but better than rack grade.

That's what I have heard as well.

No idea about that particular model, but my PTR GI gets 2.25 MOA.

I had an authentic HK91 and got terrible accuracy. It was one of the super rare polygonal ones.

Maybe the fact it was 40 years old, or had pencil barrel, or maybe being polygonal was the problem, but I didn't even get 2MOA.

I get sub-MOA with a Larue so I know it's not me.

I wonder if this HK91 clone does any better.

Isn't it a battle rifle not a sniper or marksman rifle?

Correct. The pencil profile barrel of Hk91 did not contribute to accuracy.

I wonder if the PTR-91FR does any better.

Everything I've read leads me to believe trying to make a 'precision' rifle on the 91 design is a waste of time and money with little to show for the effort.

YMMV

I have one of these rifles and used to hunt with it/shoot it a lot years ago. It shot well, would do moa with cheap federal 150gr soft points and 168 amax. Doubt it shoots that well anymore after all the steel case that's been through it and the wide hand guard that replaced the free float that came on it. Not to mention the absurd amount of carbon built up around the crown that I can't get off without fear of buggering it.

ETA: have the 16" model

HK-91 rifles have lots of issues that conspire against good accuracy.

The triggers are horrible.

There is a huge amount of reciprocating mass.

The ejection cycle is probably the most violent of any semi-auto ever produced.

Ball ammo is junk and should never be used to test the potential accuracy of any rifle. Sierra 168 grain Match King's perform very well from virtually any rifle and would be my first choice for testing purposes.

Very first run had Wilson barrels , I have one of the first xxx28 . Mine shoots well no jams and is a 2moa rifle. Some had trouble with tight chambers mine has been trouble free.

Very first run had Wilson match barrels , mine is one of the first 100 made and is a 2moa shooter with no ftf or fte problems.
